A discrete calculation method for radial load distribution integral of radial bearings

The radial load distribution integral given by Harris integral method always plays a significant role in calculating the radial load distribution of radial bearings. The error of Harris integral method for calculating the radial load distribution is found caused by the inaccurate values of the radial load distribution integral given by Harris. The radial load distribution integral is corrected in three loading stages using a discrete method. The corrected radial load distribution integral is capable of calculating the load distribution of a bearing with a small load zone caused by a light external load or a great radial clearance. The corrected radial load distribution integral shows different phases varying with the number of rolling elements participating in the radial load transfer. Some specific numerical examples show the higher accuracy and superiority of the corrected radial load distribution integral.
